I have two new autometer gauges that I want to install, an oil presseure and an oil temp. I want to take out my stock sensor for oil pressure but I need to know what size fitting I will need to go in there. I was going to use a t fitting so I can hook up both gauges here and not have to tap the oil pan. Any help that you guys could give me would be greatly appreciated. Thanks and God bless!

 

You'll need a 1/8" BSPT (M) - 1/8" NPT (F) adapter to screw into the back of the block to tee off of that. Some people simply thread a 1/8" NPT (M) into the block, and altho it can fit and seal just fine, there's always a risk of going in at the wrong angle and totally screwing it up. Then you're in trouble b/c retapping it puts metal shards into the oil supply (Although, I don't if that's pre-filter, post-filter, or somewhere in b/w that could cause harm).
